brokers who can help find call center contract with companys seeking customer service outsourcing

I am looking for experienced international brokers to help me find call center contracts for healthcare within a 6 month to one year time frame. My requirement is to outsource customer service operations in the healthcare sector, and I need brokers with experience in this type of work and who have the relevant skills and contacts to secure a successful contract. I have experience in the industry and am aware of the contractual obligations involved, so will require any brokers to be able to explain and support their advice to secure this contract. Furthermore, these international brokers should be aware of any special regulations or laws related to healthcare outsourcing contracts and be able to provide counsel accordingly. Reliability, trustworthiness and communication are key attributes that I am looking for in the successful candidate.
